exact description.

This invent-ion relates to a sanitary drinking fountain and has for itsobjects the pr0- vision of a drinking fountain which is of extremelysimple and cheaply produced construction, the provision of a fountain inwhich the water delivery part thereof is movable vertically forpresentation of the outpouring water suitably high and con.

venient to be taken in the mouth by the drinker and which on thecessation of the flow of water through the fountain will automaticallydescend to a lowered position to have a place of occupancyin a portionof the fountain in which water istrapped, so that such delivery portionis always rinsed and clean, and, furthermore, the provision ofarrangements and appliances conducing to convenience in use, and for theacquirement of advantages all as will hereinafter become apparent.

' The invention is described in conjunction with the accompanyingdrawings and is defined in the claims.

In the drawings :Figure l is a substantially vertical sectional viewcentrally through the sanitary drinking fountain with the movable partthereof in its normal position,that of disuse. Fig. 2 is a verticalsectional view on line 22, Fig. 1. Fig. 3 is a plan View, on a largerscale, of the lower end portion of the tubular or hollow cylin' dricalbody movably provided in the fountain.

Similar characters .of reference indicate corresponding parts in all ofthe views.

In the drawings, A represents the charm bered body of the drinkingfountain specifically represented as consisting of'the hollow section 10and the screw united section 12;

and into the hollow section 10 is coupled, at its inlet l) a supply pipeC, the flow of water through which is regulated by the faucet D. Thebody, has, formed in its upper section 12, a vertical passage, the wallof which at its upper portion is internally diametrically enlarged andwhich is also diametrically enlarged at its lower portion to produce therelatively upper and lower seats 03 and f. r

F represents a tube, or cylindrical body, fitted for free verticalmovements in the intermediate portion of lesser diameter of the verticalpassage 0 in the fountain body, the same being externally screw threadedat its upper and lower end portions; and G represents an annular fittingscrew threaded on the upper end of the tube and producing a shoulder atits bottom, and it has an internal undercut lip g for measurablyretarding the outflow of water thcrethrough so that for drinking thewater is delivered. in the form of a bubble or dome. The tube isprovided on its lower portion with a screw engaged cup shaped fitting Jhaving a plurality of apertures h h, and coacting therewith is anapcrtured member lc, acting as a regulating valve or register fordetermining the freevseat d for limiting the movement of the verticaltube in its descent: The tube F is filled, usually, with a body offiltering substance m, such, for instance, as powdered charcoal, thesame being retained bythe sheets i 2' of gauze or other suitableforaininous inaterlal. The wall surrounding the upper portlon of thevertical passage in the j fountain, and which is of the slightlyincreased diameter, has several transverse openings or perforations mbelow its upper edge; and the upper portion of the fountain is made withan integral bowl shaped por-- tion 0 which quite widely surrounds thewan-r delivery portion of the apparatus.

In use, when a person is desirous of drinking, he will turn on the waterto the fountain by opening the faucetD. This will have the effect ofcausing under the pressure of the water within the fountain body A theelevation of the hollow cylindrical body F from the position representedin Fig. 1 to that shown in Fig. 2, whereupon the water delivered at thesuitably high point may be drunk by bringing the.lips against and inproximity to the top of the fitting G. The freedom of delivery may, asmanifest, be regulated by the adjustment of the register device at thebottom of the tube F and, when needed, the water in passing through thetube will become filtered.

So soon'as the water is shut ofi" and the pressure within the body ofthe fountain isrelieved, the tube will fall to its normal po sition, asrepresented in Fig. l, and will remain immersed in the body of Waterleft, trapped, in the upper portion of the vertical passage which is ofthe larger-diameter, and will be thereby measurably protected from dust,dirt or other foreign matter and will be rinsed and clean at all times;'and, of

course, preparatory to drinking, the appurtenance at the upper partofthe tube will always he freshly rinsed.

In case playful children attemptto cause a squirting of thewater indelivery at the top of the fountain when the pressure is on, by placingtheir fingers over the delivery end of the passage, such effort will bede feated by reason of the perforations m which give sidewise egress forthe water obstructed at the top by way of each port m.

The fountain may be used over a sink or wash bowl and the waste oroverflow may pass from the catch bowl 0 directly into the sink, or as aprovision available when the fountain is to be used in other situations,the bowl may have a (lownuuirdly extending passaged connection piece Lso that there may be coupled thereto a waste pipe L The fountain isshown as having at the bottom of its chambered body a downwardly openingpassage 6 fonwhich a draw off cook it is provider.

\Vhile the foregoing description is one which closely follows theconstruction of sanitary drinking fountain as the same has been made,the invention, nevertheless, is not to be understood as limited in allrespects to the structural details 'herein shown and described, asvarious departures therefrom may be made within the scope of myinvention and without sacrificing any of the advantages thereof.

I claim 1. In a sanitary drinking fountain, a casing having a waterinlet thereinto and having a vertically extending passage, which at itsupper portion is diametrically enlarged,

and provided with a surrounding bowl shaped portion, a tube verticallymovable in said passage having a water inlet opening at its bottom and adelivery opening at its upper portion, said tube being adapted to berais'ed by the pressure of water upwardly thereagainst,-and means forlimiting the upwardly and downwardly returning movements of said tube. I

2. In a sanitary drinking fountain, a chambered body having a waterinlet leading thereinto and'having a vertical upwardly opening passagediametrically enlarged at its upper portion and also at its lowerportion to produce annular internal seats, a hollow cylindrical bodyfitting through and guided by the POI'lZlOILOf the chambered bodybetween its internal seats and having portions extending above and belowsaid seats and having ring shaped sections screw engaging on' its upperand lower end portions, the lower ring shaped section being providedwith a wall extending across the opening at the bottom of the hollowcylindrical body and provided with apertures, a register'plate.

pivotally mounted on the bottom of said wall and by the aperturestherein adapted ,to variably close and more or less open the aperturesin said bottom wall, a filling of filtering material in said hollowcylindrical body, and means for the retention of the latter therein. 4

3. In a sanitary drinking fountain, a chambered body having a waterinlet lead.- ing thereinto provided with means for opening and closingsame and having a draw-ofi' cock at its bottom, and also having avertical upwardly opening passage diametrically enlarged at its upperand lower portions to produce annular internal seats at the extremitiesof its relatively smaller portion, and having a bowl shaped portionsurrounding the passage, a tube vertically guided in the relativelysmaller passaged portion of the chambered body provided at itsu'pper andlower end portions with screw threads, an annular fitting screw threadedon the upper end of the tube and producing a shoulder by its bottomportion, a cup shaped fitting screw threading on the lower portionofsaid tube, producing a lower shoulder for the latter and having in thehorizontal Wall thereof'a plurality of aperturesfa register plateenacting with the said apertured wall, a body of filtering substance in-said tube, and sheets of foraminous material at the up per and lowerends of said tube held in confinement by the said screw engaged upperand lower fittings.
